Citric Acid. \ CERTIFIED ORGANIC INGREDIENTS ●
TL;DR. This ingredient is primarily used to adjust and buffer formula pH. It can also lightly chelate metal ions, which helps support color, fragrance, and preservative stability.
What does Citric Acid. \ CERTIFIED ORGANIC INGREDIENTS do in a cosmetic formula?
This ingredient is primarily used to adjust and buffer formula pH. It can also lightly chelate metal ions, which helps support color, fragrance, and preservative stability.
Is Citric Acid. \ CERTIFIED ORGANIC INGREDIENTS clean?
From a clean-beauty perspective, it is broadly accepted and has no major restricted-list friction. It is usually well tolerated at pH-adjusting levels, though very low-pH formulas or higher-use exfoliating products can feel stingy on sensitive skin.
Is Citric Acid. \ CERTIFIED ORGANIC INGREDIENTS sustainable?
This material is commonly made by fermentation of carbohydrate feedstocks such as corn, beet, or cane sugar. It is readily biodegradable, water soluble, and not associated with environmental persistence.
Is Citric Acid. \ CERTIFIED ORGANIC INGREDIENTS COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-it standards when made through allowed production routes. Its fermentation-based manufacture, low persistence, and biodegradability fit well with Green Chemistry principles.
How does Citric Acid. \ CERTIFIED ORGANIC INGREDIENTS work chemically?
The molecule is a small, highly water-soluble alpha-hydroxy tricarboxylic acid with pKa values around 3.1, 4.8, and 6.4, giving useful buffering capacity in acidic formulas. It is commonly used around 0.05% to 0.5% for pH correction, with higher levels possible in exfoliating systems, and it is stable in water-based products across typical cosmetic processing conditions.
